Major Updates and Feature Improvements Adds nucleus instance segmentation base class Adds HoVerNet architecture Adds multi-task segmentor HoVerNet+ model Adds <a href="https://www.thelancet.com/journals/landig/article/PIIS2589-7500(2100180-1/fulltext">IDaRS</a> pipeline Adds SlideGraph pipeline Adds PCam patch classification models Adds support for stain augmentation feature Adds classes and functions under tiatoolbox.tools.graph to enable construction of graphs in a format which can be used with PyG (PyTorch Geometric). Add classes which act as a mutable mapping (dictionary like) structure and enables efficient management of annotations. (#135) Adds example notebook for adding advanced models Adds classes which can generate zoomify tiles from a WSIReader object. Adds WSI viewer using Zoomify/WSIReader API (#212) Adds README to example page for clarity Adds support to override or specify mpp and power Changes to API Replaces models.controller API with models.engine Replaces CNNPatchPredictor with PatchPredictor Bug Fixes and Other Changes Fixes Fix filter_coordinates read wrong resolutions for patch extraction For PatchPredictor ioconfig will supersede everything if ioconfig is not provided If model is pretrained (defined in pretrained_model.yaml ) Use the yaml ioconfig Any other input patch reading arguments will overwrite the yaml ioconfig (at the same keyword). If model is not defined, all input patch reading arguments must be provided else exception will be thrown. Improves performance of mask based patch extraction Development related changes Improve tests performance for Travis runs Adds feature detection mechanism to detect the platform and installed packages etc. On demand imports for some libraries for performance Improves performance of mask based patch extraction
